1. Normal Dehumidify Operation
When normal dehumidify is selected, the compressor will not turn on
without a cooling demand. If dehumidify demand exists while cooling,
dry contact will also be active (24VAC removed). This output commands
variable- -speed blowers to reduce their airflow, which improves water re-
moval from the cooled air.
2. Cool to Dehumidify
The cool to dehumidify selection tells the system to operate the compres-
sor, within limits, when there is a dehumidify demand even if there is no
cooling demand. The limits are that the system may overcool up to 3_F,
but no more, while attempting to satisfy a dehumidify demand. Within
this 3_F range, there is an additional balance between overcooling and
humidity satisfaction. When overcooling must occur, the dehumidify set-
point is adjusted upward by 2% per degree of overcooling. For example,
a cooling setpoint of 76_F and a dehumidify setpoint of 60% is equiva-
lent to a cooling setpoint of 75_F and a dehumidify setpoint of 62%. This
dehumidify setpoint change is internal to the Thermidistat Control and is
not shown on the display.
